Key Parameters

Substitute Part Grouping Explanation

Substitution of the AP7342D-3330FS6-7 is determined by the following critical parameters:

• Output voltage levels (3V and 3.3V fixed outputs)
• Dual-regulator configuration (2 independent outputs)
• Maximum input voltage (5.25V)
• Operating temperature range (-40°C ~ 85°C)
• Surface mount packaging with exposed pad
• Positive fixed output configuration
• RoHS3 compliance and regulatory status

The AP7345D-3330RH4-7 qualifies as a manufacturer-recommended substitute based on matching output voltage levels, dual-regulator topology, input voltage rating, operating temperature range, and regulatory compliance. This substitute maintains functional compatibility while offering enhanced current delivery capability.

Parameter Comparison

Engineering Selection Recommendations

The AP7345D-3330RH4-7 is the manufacturer-recommended substitute for the AP7342D-3330FS6-7. Both devices maintain identical output voltage specifications, input voltage ratings, operating temperature ranges, and regulatory compliance status (ROHS3 Compliant, REACH Unaffected, EAR99 classification).

The primary difference is increased current delivery capability (300mA per channel versus 150mA per channel) and package size (8-pin versus 6-pin XFDFN). The substitute part is suitable for applications requiring equal or greater current capacity. The AP7342D-3330FS6-7 is in Last Time Buy status, making the AP7345D-3330RH4-7 the active production alternative from Diodes Incorporated.

Frequently Asked Questions (FAQ)

Q: Can the AP7345D-3330RH4-7 directly replace the AP7342D-3330FS6-7 in existing designs?

A: Direct replacement is possible if the application circuit board layout accommodates the larger 8-pin package (X2-DFN1612-8 versus X2-DFN1212-6). The substitute provides higher current capability, which is backward-compatible with designs requiring 150mA or less per output.

Q: What are the package differences between these parts?

A: The AP7342D-3330FS6-7 uses a 6-pin X2-DFN1212-6 package, while the AP7345D-3330RH4-7 uses an 8-pin X2-DFN1612-8 package. Both are surface-mount XFDFN packages with exposed pads. PCB layout modifications are required for substitution.

Q: Are the output voltage levels identical?

A: Yes. Both parts provide fixed dual outputs at 3V and 3.3V. Output voltage specifications are identical between the two devices.

Q: What is the impact of increased quiescent current in the substitute part?

A: The AP7345D-3330RH4-7 has a quiescent current of 140 µA compared to 100 µA in the AP7342D-3330FS6-7. This 40 µA difference is negligible in most applications and is offset by the enhanced current delivery capability.

Q: Are both parts RoHS compliant?

A: Yes. Both the AP7342D-3330FS6-7 and AP7345D-3330RH4-7 are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control purposes.
